Learn run button
You can start a learn run with the learn run button (S401).
Note
Two types of learn run can be carried out. See section Learn run (Page 46).
Learn run (when the supply voltage is applied)

Procedure H401 display H1 display
1. Push the door into the CLOSED position.
2. Disconnect the power supply from X3 (DC).
3. Press and hold the learn run button (S401).
4. Connect the power supply to X3 (DC).
5. Initial commissioning or motor adaptation: For the M3, M4 and M5 mo‐
tors, set the default value to 176 mm/rev. The output transmission [mm/
rev] must be congured for the other MDG3, MDG4 and MDG5 motors.
6. Press and hold the learn run button (S401)
7. The learn run starts automatically, and the learn run button can be re‐
leased.
8. During the learn run, the door is opened about 10 cm, and closed once
or twice at slow start speed. The friction of the door system is then de‐
termined by opening and closing the door once through a range of 25 cm
at slow start speed.
The door then opens and closes through its complete range of movement
at reduced speed. After the door has opened by approximately 15 cm, it
passes through an additional short acceleration ramp to determine the
mass to be moved.
9. The door parameters and the determined door width are saved when the
door is in the CLOSED position.
This means that the door width and the mass to be moved are re-adapted
and saved. The default parameters for energy limitation, speed limita‐
tion, friction compensation and all other driving curve parameters are
also loaded.
10. Learn run completed.
11. First commissioning or motor adaptation. The currently determined door
width is output on the terminal module for the M3, MDG3, M4, MDG4,
M5 and MDG5 motors.
